The battery-operated PFM-711A Field Meter is a compact electronic "chopper"
design with accuracy of ± 2% at ambient conditions (23ºC and 30%
Rh). It features automatic polarity, measurement "Hold" button, low-battery
indicator, high and low ranges, distance ranging lights for accurate and repeatable
measurements, manual zero control and a ground snap. With two supplied analog
output cables, it can be used in conjunction with an X-Y plotter, the PDT-740B
Static Decay Timer or any analog data recording device.

The CPM-720A Charge Plate Assembly is 3.25 inches square. It attaches to the
PFM-711A field meter for ionizer balancing, per STM3.1, voltage or charge
generation, charge decay and voltage suppression analysis.

The PDT-740B Static Decay Timer provides voltage decay time measurements of
ionizers and controlled materials from 1,000 volts to 100, 50 or 10 volts. Used
with the PFM-711A, it furnishes automatic reset and timing functions, LED status
indicators and displays decay time from 0.2 to 159.9 seconds.

The PHT-771 uses a capacitive sensor to provide accurate temperature and humidity
readings. This instrument includes a sample "Hold" function and a "Min/Max"
button to view different levels reached during the measurement period.

The PFK-101 includes a modified wrist strap for instrument and personnel grounding,
a common point ground adapter plug and an operator's manual, all packaged in
a specially designed carrying case.
